Negatively charged nitrogen-vacancy (NV) centers were created in high quality IIa diamonds by nitrogen (N) implantation. To identify implanted N atoms and their incident position, micro ion beams of N (natural abundance 0.37%) were applied. Since the reduction of C affects an increase in T, N implantation into a CVD diamond with high purity of C (99.99%) was carried out. As a result, the value of T for both NV and NV centers (NV centers are created from N atoms originally existing in the diamond and vacancy introduced by implantation after annealing) was obtained to be about 2 ms. By optically detected magnetic resonance (ODMR) measurements, the creation yield of both NV and NV was estimated.

We have measured optically-detected magnetic resonance (ODMR) of single spin of NV center in a high purity C enriched CVD diamond created by N ion implantation. Detailed ODMR measurements of individual NV centers revealed that both NV and NV were created by the N implantation with a ratio of [NV]/[NV] 1 and a high conversion yield of 70-100% for [NV+NV]. The spin coherence time of was measured to be 2 ms at room temperature, which is the longest ever recorded in implanted samples. This result is expected to have a significant impact on realizing NV based applications.
